## Usage
OSC will only work if you run the REPL locally + the OSC server besides it:
Assuming you have [node.js](https://nodejs.org/) installed, you can run the osc bridge server via:
From the project root:
```js
npm run repl
```sh
npx @strudel/osc
```
and in a seperate shell:
```js
npm run osc
```
This should give you
You should see something like:

Now open Supercollider (with the super dirt startup file)
### --port
Now open the REPL and type:
By default it will use port 57120 for the osc client, which is what [superdirt](https://github.com/musikinformatik/SuperDirt) uses. You can change it via the `--port` option:
```js
s("<bd sd> hh").osc()
```sh
npx @strudel/osc --port 7771 # classic dirt
```
or just [click here](https://strudel.cc/#cygiPGJkIHNkPiBoaCIpLm9zYygp)...
### --debug
To log all incoming osc messages, add the `--debug` flag:
```sh
npx @strudel/osc --debug
```
## Usage in Strudel
To test it in strudel, you have can use `all(osc)` to send all events through osc:
```js
$: s("bd*4")
all(osc)
```
[open in repl](https://strudel.cc/#JDogcygiYmQqNCIpCgphbGwob3NjKQ%3D%3D)

Generally, the idea with chaining is that code such as `a("this").b("that").c("other")` allows `a`, `b` and `c` functions to happen in a specified order, without needing to write them as three separate lines of code.
You can think of this as being similar to chaining audio effects together using guitar pedals or digital audio effects.

Whether you're using a synth or a sample, you can apply any of the following built-in audio effects.
As you might suspect, the effects can be chained together, and they accept a pattern string as their argument.
# Signal chain
<img src="/img/strudel-signal-flow.png"></img>
The signal chain in Strudel is as follows:
- An sound-generating event is triggered by a pattern
- This has a start time and a duration, which is usually
controlled by the note length and ADSR parameters
- If we exceed the max polyphony, old sounds begin to die off
- Muted sounds (one whose `s` value is `-`, `~`, or `_`) are skipped
- A sound is produced (through, say, a sample or an oscillator)
- This is where detune-based effects (like `detune`, `penv`, etc. occur)
- The following will occur _in order_ and only if they've been called in the pattern. Note that all of these are
single use effects, meaning that multiple occurrences of them in a pattern will simply override the values
(e.g. you can't do `s("bd").lpf(100).distort(2).lpf(800)` to lowpass, distort, and then lowpass
again)
- Phase vocoder (`stretch`)
- Gain is applied (`gain`)
- This is where the main (volume) ADSR happens
- A lowpass filter (`lpf`)
- A highpass filter (`hpf`)
- A bandpass filter (`bandpass`)
- A vowel filter (`vowel`)
- Sample rate reduction (`coarse`)
- Bit crushing (`crush`)
- Waveshape distortion (`shape`)
- Normal distortion (`distort`)
- Tremolo (`tremolo`)
- Compressor (`compressor`)
- Panning (`pan`)
- Phaser (`phaser`)
- Postgain (`post`)
- The sound is then split into multiple destinations
- Dry output (amount controlled by `dry` parameter)
- The sends
- Analyzers
- These are used for tooling like `scope` and `spectrum` and their setup usually happens behind the scenes
- Delay (amount controlled by `delay` parameter)
- Reverb (amount controlled by `room` parameter)
- The dry output, delay, and reverb are joined into what is called the "orbit" of the pattern (see more in the section below)
- The `duck` effect affects the volume of all signals in the orbit
- The orbit is then sent to the mixer
## Orbits
Orbits are the way in which outputs are handled in Strudel. They also prescribe which delay and reverb to associate with the dry signal.
By default, all orbits are mixed down to channels `1` and `2` in stereo, however with the "Multi Channel Orbits" setting
(under Settings at the right) you can use them as individual 2 channel stereo outs (orbit `i` will be mapped to
to channels `2i` and `2i + 1`). You can then use routers like Blackhole 16 to retrieve and record all of the channels in a DAW for later processing.
The default orbit is `1` and it is set with `orbit`. You may send a sound to multiple orbits via mininotation
<MiniRepl client:visible tune={`s("white").orbit("2,3,4").gain(0.2)`} />
but please be careful as this will create three copies of the sound behind the scenes, meaning that if they are mixed
down to a single output, they will triple the volume. We've reduced the gain here to save your ears.
⚠️ There is only one delay and reverb per orbit, so please be aware that if you attempt to change the parameters on two
patterns pointing to the same orbit, it can lead to unpredictable results. Compare, for example, this pretty pluck
with a large reverb:
<MiniRepl
client:visible
tune={`
$: s("triangle*4").decay(0.5).n(irand(12)).scale('C minor')
.room(1).roomsize(10)`}
/>
versus the same pluck with a muted kick drum coming in and overwriting the `roomsize` value:
<MiniRepl
client:visible
tune={`
$: s("triangle*4").decay(0.5).n(irand(12)).scale('C minor')
.room(1).roomsize(10)
$: s("bd\*4").room(0.01).roomsize(0.01).postgain(0)`}
/>
This is due to them sharing the same orbit: the default of `1`. It can be corrected simply by updating the orbits to be
distinct:
<MiniRepl
client:visible
tune={`
$: s("triangle*4").decay(0.5).n(irand(12)).scale('C minor')
.room(1).roomsize(10).orbit(2)
$: s("bd\*4").room(0.01).roomsize(0.01).postgain(0)`}
/>
## Continuous changes
As all of the above is triggered by a _sound occurring_, it is often the case that parameters may not be
modified continuously in time. For example,
<MiniRepl
client:visible
tune={`
s("supersaw").lpf(tri.range(100, 5000).slow(2))`}
/>
Will not produce a continually LFO'd low-pass filter due to the `tri` only being sampled every time the note hits
(in this case the default of once per cycle). You can fake it by introducing more sound-generating events, e.g.:
<MiniRepl
client:visible
tune={`
s("supersaw").seg(16).lpf(tri.range(100, 5000).slow(2))`}
/>
Some parameters _do_ induce continuous variations in time, though:
- The ADSR curve (governed by `attack`, `sustain`, `decay`, `release`)
- The pitch envelope curve (governed by `penv` and its associated ADSR)
- The FM curve (`fmenv`)
- The filter envelopes (`lpenv`, `hpenv`, `bpenv`)
- Tremolo (`tremolo`)
- Phaser (`phaser`)
- Vibrato (`vib`)
- Ducking (`duckorbit`)

# Xen Harmonic Functions
These functions allow the use of scales other than your typical chromatic 12 based ones.
### tune(scale)
<JsDoc client:idle name="tune" h={0} />
Here's an example of how to configure a basic hexany scale:
<MiniRepl client:idle tune={`"0 1 2 3 4 5".tune("hexany15").mul("220").freq()`} />
Try other scales like `hexany1`, `iraq`, `gumbeng`, `gunkali`, or `tranh3`
For a full list of available scales from tunejs, see http://abbernie.github.io/tune/scales.html
You can set your root to be a particular note with `getFreq`
<MiniRepl
client:idle
tune={`"4 8 9 10 - - 5 7 9 11 - -".tune("tranh3")
.mul(getFreq('c3'))
.freq().clip(.5).room(1)`}
/>
Some tunings become more pronounced with a longer reverb decay:
<MiniRepl
client:idle
tune={`"<[5 6 8 10] - [5 7 9 12] -> -".tune("gumbeng")
.mul(getFreq('c3'))
.freq().clip(.8).room("3:10").rdim(10000).rfade(5)`}
/>
Additionally, you can combo this with `fmap` so that the base note changes:
<MiniRepl
client:idle
tune={`"9 11 12 10 - - -".tune("gunkali")
.mul("<c3 c3 a3 d#3>".fmap(getFreq))
.freq().legato("2 .7").room("1:15").rdim(8500).rlp(14000).rfade(8)`}
/>
Combining this with various polyrhythm tricks can become very evocative:
<MiniRepl
client:idle
tune={`"<[0 3 1 -] [-1 4 2 8]> ~ ~,<-4 -5>"
.transpose(4)
.tune("iraq")
.mul("<c3 d3 c#3>".fmap(getFreq))
.freq().clip(.5).room(1).rfade(9)`}
/>
Another helpful trick when exploring new tunings is to strum them.
Many have a much more enchanting sound that was chosen over many generations of musicians for being strummed.
Take the `sanza` tuning:
<MiniRepl
client:idle
tune={`"4 5 6 7 8 9".tune("sanza")
.mul(getFreq('c3'))
.freq()`}
/>
Notes 7 and 9 will clash quite a bit if you arp them normally. Many tunings will have this sort of sound, and it can feel distracting on its own.
See how close they are on the pitch wheel?
<MiniRepl client:idle tune={`"[7 9]!3".tune("sanza").mul(getFreq('c3')).freq()._pitchwheel()`} />
This quality is often due to how the tunings were formed with instruments that were played differently than a piano.
As such, some tunings are much better strummed, with the subtle clash of the detuned notes actually making the sound much more magical:
<MiniRepl
client:idle
tune={`"[0 1 2 3 4 5 6]@0.3 -"
.transpose("<2 5 8 1>")
.tune("sanza")
.mul(getFreq('c3')).freq()
.legato("3").room(1).rfade(5)`}
/>
Note the legato and reverb effects make sure the sound of the strumming gets to wash together. Alternating the direction of the strum can make the
tones sound even more alive, too.
The `tranh3` tuning has a similar set of notes, with two clashing. You might trying plugging that in above and see if you find a favorite strumming pattern.
